The paper analyses topicalities of implementation of business rules and business rules management systems into enterprise business management information systems. It is rare nowadays to find a company which is not using an ERP (Enterprise Resource Planning) system for its own needs. These systems are intended to perform a centralized accounting of enterprise activities, including financial, logistic, production, service management and human resource management accounting. / Darbe analizuojamas verslo taisyklių bei verslo taisyklių valdymo sistemų (angl. rule engine) taikymas įmonių verslo valdymo (angl. Enterprise Resource Planning – ERP) sistemose, nagrinėjamos šio taikymo problemos.

Šiuo metu tiek pasaulio tiek Lietuvos IT rinkoje sukurta daug dokumentų valdymo sistemų, kurios yra įdiegtos įvairiose srityse, sportas - ne išimtis. Šio darbo pagrindinis tikslas – patrauklesnės treniruotės apskaitos sukūrimas bei prieinamesnių, lankstesnių ir efektyvesnių treniruotės planavimo metodų užtikrinimas. Darbo uždaviniai - tyrimu įvertinti sukurtos sportininkų treniruotės krūvio planavimo ir valdymo sistemos kokybę ir pateikti siūlymus tolesniam jos tobulinimui. / The main goal of the project is to find out the appropriate way to keep favorable workout record, to create possible methods to evaluate workout effectiveness as well as provide flexible and accessible workout planning techniques. The present bachelor’s paper aims at major factors, which influence workout planning and the quality of management system. Management quality has been examined using tests as well as code analysis. The main characteristics were evaluated according to set ISO-9126 standard. Fundamental characteristics have been analyzed; the real data has been used. It meets specifications for functional requirements, is quite flexible and allows to evaluate workout quality accurately.

The properties of linear induction motor and areas of its application are analyzed; frequency converters and their control methods are discussed in this final work. Methods to realize a pulse width modulation are analyzed, scalar and vector control principles as well as perspectives of perfection of semiconductor commutating elements and control systems are discussed. The principle of operation of control systems applied in frequency converters is analyzed On the base of analysis mathematical and Simulink model of linear induction motor in α-β reference frame is developed, mathematical and Simulink models of frequency controlled linear induction drives are carried out. Two models of linear frequency controlled induction drive: scalar and vector control are investigated, transient characteristics of inverter output voltage, currents of linear motor, developed force and linear speed are analyzed and results of different control principles are compared.
